Just received our 2018 Casita last week from Rice, TX. We had them pre-wire it for solar. So there is a port on the side of my casita for the solar connection. Can I just buy the solar panel and plug it in and it's good to go? Or do I need to order the whole set up; charge controller, inverter, etc.?
Also, I'm aware that they are pre-wired for "Zamp" panels which means the polarity is reversed.
